i IMPROVEMEN'I IN EYELETINGMACHINES.

Specification forming part of Letters Patent No. 37,306, dated January 6, 1863.

To all whom it may concern.-

Beit known that I, JOSEPH F. SARGENT, of Boston, in the county ot Su'olk,in the State of Massachusetts, have invented a new and Improved Eyeleting-Machine and Ido hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sutieient to enable those skilled in the art to practice it.

My invention relates to certain improvements in machines for setting eyelets; and it consists in certain arrangements and combinations of parts, and in the peculiar construction of details by which eyelets, when thrown promiscuonsly into a hopper, are brought into the position proper for their presentation, one after another, to be fed to the work and placed therein in readiness to be clinched, and by which also other eyelets which do not assume the proper position are discharged from the machinery; also, in the arrangement, substantially as herein described, of those portions of the sets which operate on the ends of the eyelets with reference to the fulcrums of the levers carrying the sets; also, in the combination,with the setting or clinchin g mechanism, and so as to operate with it and at the same time, of one or more punch es, which form holes into which the eyelets are inserted, and which space the distances between the eyelets, and, also, in the details by which the whole machine and sundry of its parts are operated.

The drawings illustrate a machine embodying my invention and sundry modificationsv thereof, and in all the figures similar letters refer to similar parts.

Figure lis a side elevation of said machine. Fig. 2 is a plan, and Fig. 3 a front end view, thereof. Fig. etshows in sectional elevation the hopper, the eyelet-arranging apparatus, the chute, and the throat in the bed on which the work rests, together with the eyelet-feeder, in elevation and also in plan. Fig. 5 shows the small hand-wheel, which has a ratchetwheel connected therewith, and is keyed fastto the shaft. Fig. 6 is a section taken on the line :v x. (Seen in Fig. l.) Fig. 7 is asection across the chute, showing the sides thereof and their under-cut. Fig. 8 is a section taken in a plane passing through the axial line of the sets. Fig. 9 is a similar section taken in the same plane, and showing an eye let as clinched in the work. Said gure also embraces a view of an eyelet before operated on by the sets. Fig. 10 shows in plan and in side elevation so much of the hopper, the eyelet-arrangin g apparatus, and chute as is necessary to show the manner of connecting a' brush therewith so that it can vibrate near the guard in the chute to displace therefrom any eyelets which may not have been properly shaken into position for presentation to the work of the feeder. Fig. ll shows in section a throat arranged so that it can be changed for throats of different sizes to suit different very convenient for right and left hand work which occurs in shoes and elsewhere.

The bed a of the machine, on which the work or goods may be placed to be eyeleted, forms part of the frame which supports the shaft b and the upper and lower levers, c and d. The loose pulley e can rotate round shaft b, and carries the pawl f, said pulley having an eye upon it to which a string may be fixed,

which is passed tc treadle, so that by operating the treadle halt' a turn may be given to i the cam-shaft b by the pawlf engaging in the ratchet g, which, with asniall hand-wheel, is made fast on the shaft. A spring is so conibined with the treadle as to raise it when relieved from pressure, and thereby the loose pulley and pawl are, by means of the other part of the string, rotated backward, ready for the pawl to catch in the other notch of the ratchet, to give to the sh aft b another half-revolution with the next depression of the treadle. The cams h and t' are fixed on the shaft, the

first operating to work the levers c and d, and

the last to work the vibrator s through the intervention of the lever j, aided by'a spiral f spring. The lower lever, al, is pivoted to the frame, so that its fulcrum is in the line of the surface of the bed, and the upper lever has its fulcrum about as much higher than the surface of the bed as the average thickness 4of the stock to be eyeleted, which arrangement brings the liange-formin g portions of thesetsI square with the axis of the eyelet in the iinal clinching operation.

0n reference to the drawings it will be observed that the arrangement of the levers c and d with reference to the sha"t b and cam h is such that the upper set moves first and nearly completes its downward motion before the upward motion of the lower set begins. Thus, the upper set is thrust into the eyelet while in the throat, and when at rest the lower set receives its motion, which is of less extent and of greater power, (as will be seen on inspection of the relative position of the ful: crums of i the two levers,) and clinches the eyelet against the upper set while stationary. The hopper into which eyelets are emptied promiscuously is at 7c, and isplaced on an ineline with two bars leading therefrom, which have a vibratory bottom piece, s, and a cover, t. These bars are placed nearly parallel at a distance apart somewhat greater than any dimensions of the eyelets, and the bottom piece is best covered with leather, and is made to move transversely, by means before mentioned, a distance a little in excess ofthe distance apart of the side bars. This motion of s causes all or nearly all of the eyelets to assume a standing position upon their formed flanges before and as they pass out from under the cover t and away from the shaking action. The -sides of the chute, which extend from beyond t in an inclined direction till it enters the throat, narrow tonearly t the size of the eyelets, and are beveled under to receive the flanges thereof, which slide under this beveled or undercut formation, which is best shown in Figs. 4, 6, 7, and ll. At a convenient place in the narrow part of the chute a guard, l, is placed over it and inclined to its general direction, so that all eyelets which have assumed a proper position can pass beneath the guard, it being observed that when the eyelets rest upon their flanges they occupy less height than when upon their sides. All eyelets which pass down the chute upon their sides strike against the guard l, and are thereby deflected into a suitable receptacle at m, from which they may be transferred at the will of the operator to the hopper. The guard l, from a height above the bottom of the chute suiicient to admit the passage beneath it of eyelets standing on their ends, has a flange turned downward toward the bottom of the chute and through which portion of the guard a notch is cut sufficient to admit the passage of the small ends of the eyelets, but which will not pass the llange of an eyelet standing on its small end. Eyelets thus standing are thereby checked in passing down the chute, and as they are not held by their flanges in the undercut formation of the sides of the chute, the eyelets fall into the receptacle placed to receive them where the sides of the chute are cut away or are depressed. J ust above the guard l one or both sides of the chute are cut away so far down as to leave only the beveled formation, underneath which the flanges of the properly-placed eyelets slide. This is done so as to let the improperly-placed eyelets roll out ot' the kchute when they strike the guard, and this action may be insured by the vibrations of a brush arranged as seen in Fig. l0, which plays above the level of properly-placed eyelets or by any other suitable arrangement. The sides of the chute are so arranged as to be adjustable laterally to suit eyelets of different diameters. The chute terminates in the throat with its bottom on a level with the end of the lower set, when in its lowest position, and through the bottom of the chute, inrclose proximity to the throat, an instrument n, operates to feed at the proper time the eyelets which slide down the chute into the throat, and also to prevent their passage into the throat at all other times. This feeder 'n is operated like many of the four-motioned feeders in sewing-machines, from a sliding bar, o, which is made to reciprocate it by being drivl en forward by pins p in h, and backward by an incline, k, made fast to d, which incline can have more or less pitch given to it, so as to adjust the throw of the feeder to the exact size of the eyelets. The cams used for operating the parts may be single-faced, with springs applied to act in conjunction, or path-cams may be used, dispensing with the springs, which arrangement will make the machine work with less resistance and more evenly than it will when springs and single-faced, cams are used.

The bed of the machine is supplied with wooden or soft-metal pieces for the punches to act upon, which punches are made adjustable with reference to the sets, so as to gage the distance apart of the holes into which the eyelets are to be clinched. 'In addition to the punches, the upper lever may be provided with a yielding presser-foot, r, to act upon the stock, though this presser-foot is not absolutely needed, especially when the shoulder of the upper set is made as proportionately large as where shown in Fig. 9.

The operation of and upon the eyelets near the throat of the machine is as follows: The feeder is down below the bottom of the chute when the lower set lls the throat, and thus permits, in beginning to operate the machine, the eyelets to slide down against the set; but before the set falls quite to the bottom of the chute the feeder rises, and, entering into one or more of the eyelets, according as it is provided with one or more points, holds the descending eyelets from crowding the one most advanced into the throat upon the complete descent of the lower set, but when this has reached its lowest position, then the feeder moves forward and pushes the eyelet in advance of it into the throat, then the upper set thrusts its point through the hole previously made by the punch in the stock, and which has been placed directly beneath by the operation and into the eyelet, and the lower set rises with reference to the upper set as hereinbefore explained 5 but while the lower set has been rising in the throat, driving the eyelet through the stock and upward on the point of the upper setand clinching it against the shoulder of the upper set, the feeder has been descending below the bottom of the chute and retreating the distance of the size of one eyelet in readiness to rise again into the eyelets before the lower set again reaches the level of the bottom of the chute in the continued action of the machine.

I claiml. The combination of a hopper with two side bars and cover and a vibratory bottom, constructed, arranged and operating substantially as specified.

2. The undercut formation of the sides of the chute, provided with the guard or deflector and a depression in the side boundary of the chute when arranged and operating together substantially as and for the purpose specified.

3. The arrangement of those parts of the sets which operate on the ends of the eyelets relatively to the pivots or fulcrums from. which the sets are vibrated, substantially as described.

4. In combination witha hollow set, a feeder having a point or points suitable for entering into an eyelet or eyelets, and motions forward and backward for the purpose of feedin g, and motions toward and from the eyelets for the purpose of engaging with them, said combination operating to place successively and at the proper times one eyelet after another on the hollow set, and at all other times in conjunction with the set to prevent the eyelets from being placed thereon.

5. The combination of apunch with an eyelet set, so that the punch will operate t0 form holes in advance of the place where the set operates and to spacel the distances between the holes, substantially as described.
